What is the sticker made of? The main steps are as follows:

I. base material

1. Paper base material

Paper base materials are divided into: offset paper, coated paper, glass cardboard, laser paper, kraft paper, fluorescent paper, gold-plated paper, aluminum foil paper, fragile (anti-counterfeiting) paper, silver plated paper, masking paper, cloth label (Tyvek / nylon) paper, pearlescent paper, sandwich coated paper and variable information paper.

2. Film substrate

The film substrate can be divided into transparent polyvinyl chloride (PVC), polyester (PET), polypropylene (PP), polycarbonate (PC), synthetic paper, PS, PE, shape memory anti-counterfeiting material (SMP), etc.

II. Coating material

Transparent polyester (PET), translucent polyester (PET), transparent oriented polypropylene (OPP), translucent oriented polypropylene (OPP), transparent polyvinyl chloride (PVC), glossy white polyvinyl chloride (PVC), matte white polyvinyl chloride (PVC), synthetic paper, glossy gold (silver) polyester, matte gold (silver) polyester, shape memory anti-counterfeiting material.

III. adhesive

General Super Sticky type, general strong sticky type, refrigerated food strong sticky type, general re uncovering type, fiber re uncovering type. On the one hand, it can ensure the proper adhesion between the backing paper and the surface paper, on the other hand, it can ensure that the surface paper can be peeled off and has strong adhesiveness with the paste.

IV. bottom material

Release paper is commonly known as "backing paper". Its surface is not sticky with low surface energy. Backing paper has an isolation effect on adhesive, so it is used as the attachment of facing paper to ensure that the facing paper can be easily peeled off from the backing paper. Commonly used are white, blue and yellow grasin paper (glass) or garlic paper (onion), kraft paper, polyester (PET), copperplate paper, polyethylene (PE).
